To win the 100 pound offered in connection with this challenge, the man taking it up had first to lift overhead in the “One Hand Anyhow” style this barbell loaded to a poundage equivalent to 1 1/2 times his own weight, after which a kettlebell representing a third of the barbell poundage had to be lifted overhead with the other hand.
This “double-bodyweight” feat of W.A. Pullum was performed twelve times a week at music halls. The Challenge, however, was never accepted.
